Module 7
This module is used to permit the PLC to send any unicast messages while
Module 3 is reserved for the efficient handling of Data Table 6 and to quickly
send these parameters to their respective nodes. Module 7 is provided
primarily to send out other unicast messages.
Module 8
The assignment to each gun is sequential, that is to say, the first byte of
Module 8 is assigned to gun #1, the second byte is assigned to gun #2, and
so on. The value in these bytes is a new preset number which is to be used
by a given gun, and is sent to that gun’s KV and Flow node−pair via the
Data Table 14 command (using multicast addressing). When the gateway is
initialized, it will fill this space with zeros indicating to the gateway there is
no change to the current preset (all nodes, by default, start up using preset
#1). It is up to the PLC programmer to initialize this space to contain all
ones, but it is not necessary. The PLC program may change a gun to a new
preset by simply writing to that gun’s byte in Module 8. When the gateway
detects a change has occurred in any of the bytes in this module, it sends a
multicast message out to the node−pair associated with that byte (gun).
Therefore, as the gateway polls its way through Module # 8 looking for
changes, it is possible for it to send out 32 multicast messages; one for
each byte change detected. The last 32 bytes in this module are not used.
Module 9
This module contains 2 bytes. One byte defines which information the
Gateway should present to the PLC. The second byte defines which
grouping of guns to display. This process is similar to module 4 where 0
equals guns 1−4, 1 equals guns 5−8, and so on. For instance, a 1 in the
first byte and a 0 in the second byte will cause the Gateway to pass the gun
node maintenance time for guns 1−4 to the PLC.
All of the above IO Modules are discussed in more detail in later sections.
